As a result, the restoring force of the spring 15 will cause the elongate metal lock bar 2 to be inserted into the lock hole of the cage body and the door body is locked by the locking apparatus.
- a locking apparatus in accordance with the present invention includes as an advantage that rotating the turntable around its centre point results in the simultaneous linear movement of the one or more elongate metal bars to cause the locking or opening of the door body.
- This arrangement is very convenient and ergonomic to operate and effectively locks the door body to the cage body as has been described above.
- the configuration of the connecting member provides an arrangement where a pair of elongate metal lock bars can extend in opposed directions from the centre of the locking apparatus with respect to the turntable and this configuration provides improved stability of the locking apparatus as the forces are balanced.
- Another advantage is that connecting the elongate metal lock bar to the connecting member does not require multiple bends in the elongate metal lock bar.

- Illustrative embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only illustrative and exemplary.
- For ease of description, the locking apparatus of the present invention is described below in its usual assembled position as shown in the accompanying drawings and terms such as front, rear, upper, lower, horizontal, longitudinal etc., may be used with reference to this usual position.
- As shown in
Figure 1 , a pet cage includes a cage body, the cage includes a door body made of grid metal strips, and a pet cage locking apparatus 1 is mounted on the door body. - As shown in
Figure 2 , the locking apparatus 1 includes two elongate metal lock bars 2, a turntable 3 that is rotatable about an axis of rotation and a connectingmember 4 is provided which operably connects the elongatemetal lock bar 2 and the turntable 3. The connectingmember 4 includes a forwardly extendingportion 41 and a rearward extendingportion 42 which extends parallel with and is outwardly offset from the forwardly extendingportion 41. The forwardly extendingportion 41 is configured to receive a front section of the elongatemetal lock bar 2 and fix a retained end of the elongatemetal lock bar 2. The elongatemetal lock bar 2 is configured to extend along a radial line originating from the axis of rotation of the turntable 3, that is, the extension line of the elongate metal bar would passes through a mirror plane of the turntable, the mirror plane of the turntable 3 being perpendicular with a plane where the turntable is located and extending through the axis of rotation. A linear conversion mechanism is arranged between the turntable 3 and the rearward extendingportion 42 of the connectingmember 5. When the turntable 3 rotates around the axis of rotation, the linear conversion mechanism is configured to convert rotation of turntable 3 to linear movement of the connectingmember 4 in the same direction as a longitudinal direction of the elongatemetal lock bar 2. - In one example, the linear conversion mechanism includes a first circular projection 6 located on an upper surface of the rearward extending
portion 42. An elongate radially extendingslot 5 is provided at an eccentric or off-centre position of the turntable 3, and the first circular projection 6 is received in theelongate slot 5. As shown inFigures 3 to 5 , when the turntable 3 rotates around the central axis of rotation, theelongate slot 5 on the turntable 3 applies a force to the first circular projection 6 on the rearward extendingportion 42 which drives the connectingmember 4 to perform a linear movement in the longitudinal direction of the elongatemetal lock bar 2. In this manner, theelongate slot 5 on the turntable 3 has a circular arc-shaped motion trajectory and the first circular projection 6 has a motion trajectory consistent with a linear trajectory of the elongatemetal lock bar 2. - As shown in
Figures 9 and 10 , the locking apparatus 1 further includes a generally rectangular metal base plate 9 mounted on the door body of the pet cage, for placing the elongatemetal lock bar 2 and the connectingmember 4 etc. The elongatemetal lock bar 2 extends over an upper surface of the metal base plate 9 from a central position on a side of the metal base plate 9 improving the overall stability of the metal base plate 9. The connectingmember 4 reciprocates linearly on the metal base plate 9. - According to conventional methods, the metal lock bar would be bent twice and then connected with the
elongate slot 5 on the turntable 3.This bending process of the metal lock bar can be difficult to achieve. Further, movement of a round metal lock bar is not very stable. In this example, the connectingmember 4 of the present invention is integrally injection molded from a plastic material, and the elongatemetal lock bar 2 is connected to the turntable 3 through the connectingmember 4 so that the bending process of the metal lock bar may be simplified and the reliability of the structure is enhanced. - In this illustrative embodiment, metal base plate 9 includes
side abutment portions 10 for limiting sideways or lateral movement during linear movement of the connectingmember 4 on the metal base plate 9 which in this example are formed by stamping the metal base plate 9. As can be seen in this example, a side surface of the connectingmember 4 is a plane structure and is matched with theside abutment portion 10. - Additionally, in this example, end abutment portions 11 are provided on the metal base plate 9, and the end abutment portions 11 are formed by stamping on the metal base plate 9. Two end abutment portions 11 are provided correspondingly to one connecting
member 4, a first end abutment portion 111 being located at the front end of the rearward extendingportion 42, and a secondend abutment portion 112 being located at the rear end of the rearward extendingportion 42. The provision of the first end abutment portion 111 and the secondend abutment portion 112 both function to limit the magnitude of the linear movement of the rearward extendingportion 42 on the metal base plate 9. As a result, the elongatemetal lock bar 2 is confined to linear motion trajectory on the metal base plate 9. - Additionally, as shown in
Figures 11 to 13 , rearward extendingportion 42 of connectingmember 4 comprises an open-ended 17U-shaped channel 16 for receiving aspring 15. The opposed end ofU-shaped channel 16 is closed and provides a stop against a first received end of thespring 15 and the free end ofspring 15 abuts the secondend abutment portion 112 on the metal base plate 9. As shown inFigure 10 , the shape of the secondend abutment portion 112 matches the cross sectional shape of theU-shaped channel 17. When the rearward extendingportion 42 is moved rearward, the secondend abutment portion 112 compresses thespring 15 and is received into theU-shaped channel 17 and the spring provides a return force to urge the connectingmember 4 forward. - In operation, the turntable 3 is manually turned via a
button 21, and theelongate slot 5 on the turntable 3 drives the first circular projection 6 on the rearward extendingportion 42 so that the rearward extendingportion 42 and the elongatemetal lock bar 2 are moved backward. At this time, thespring 15 is compressed, the elongatemetal lock bar 2 is moved backward and then moved out of a lock hole located on the body of the pet cage and the door body may be opened. At this time, small animals in the pet cage can be taken out or put in. - When
button 21 is released, the connectingmember 4 and the elongatemetal lock bar 2 are both moved forward under the elastic action of thespring 15. Therefore, when it is necessary to close the door body, the turntable 3 is also first rotated so that thespring 15 is in a compressed state. Thereafter, when an outer end of the elongatemetal lock bar 2 is aligned with the lock hole of the cage body, the turntable 3 is released. As a result, the restoring force of thespring 15 will ensure that the elongatemetal lock bar 2 is inserted into the lock hole of the cage body and the door body is locked by the locking apparatus. - As shown in
Figures 11 and 12 , afirst groove 12 for containing the elongatemetal lock bar 2 is provided on a lower side of the forwardly extendingportion 41, and alimit rib 13 for limiting the up-and-down movement of the elongatemetal lock bar 2 is provided on two sidewalls of thefirst groove 12. A throughhole 14 is provided on an inner end of the forwardly extendingportion 14. As shown inFigure 2 , an inner end of the elongatemetal lock bar 2 is bent at 90 degrees to form aforce receiving end 211 which is hooked in the through hole 14.When the connectingmember 4 performs a linear reciprocating movement, the elongatemetal locking bar 2 hooked in the throughhole 14 is also driven to reciprocate linearly.Limit rib 13 functions to prevent the elongatemetal lock bar 2 from falling out of the connectingmember 4. - As shown in
Figure 13 , a lower end of the turntable 3 is mounted on the metal base plate 9, and ahousing 18 is mounted on the metal base plate 9. As shown inFigure 2 , the metal base plate 9 and thehousing 18 are fixed to each other by a first snap fit arrangement. The first snap fit arrangement includes a first connection aperture 19 provided on the metal base plate and a first resilient lug orprojection 20 on thehousing 18. A button orknob 21 for driving the turntable 3 to rotate is provided on the centre of thehousing 18. As shown inFigures 17 and 18 , the button orknob 21 and the turntable 3 are attached together by a second snap fit arrangement which comprisesperipheral slots 22 located on thebutton 21 that receive and attach to correspondingprotrusions 23 on the turntable 3. - As would be appreciated, the locking apparatus 1 for a pet cage as provided with the
housing 18 is more integrated and has a more compact appearance and the further provision of thebutton 21 allows the user to open and lock the door body more conveniently and ergonomically. - Other parts of the present embodiment are the same as those of the first embodiment except that in this illustrative embodiment as shown in
Figure 19 andFigure 20 , the linear conversion mechanism may also include atransverse groove 8 located on the rearward extendingportion 42 and extending perpendicular to a longitudinal direction of the rearward extendingportion 42 and a secondcircular projection 7 located at an eccentric or off-centre position on the turntable 3 where the secondcircular projection 7 is located in thetransverse groove 8. - In this embodiment, the
transverse groove 8 includes agroove front wall 81 and a grooverear wall 82; and as shown inFigures 6 to 8 , the secondcircular projection 7 of the turntable 3 is located in thetransverse groove 8 of the rearward extending portion 42.The process of opening the door body is exemplified as follows: the turntable 3 is manually rotated via the knob orbutton 21 and the secondcircular projection 7 on the turntable 3 applies a compressive force on the grooverear wall 81 of thetransverse groove 8 to drive the rearward extendingportion 42 and the elongatemetal lock bar 2 to move backward together. At this time, thespring 15 is compressed and the elongatemetal lock bar 2 is moved out of the lock hole of the cage body, and the door body of the pet cage may be pulled open. - In this process, the motion trajectory of the second
circular projection 7 on the turntable 3 is arc-shaped, and the motion trajectory of thetransverse groove 8 is linear. When the hand leaves thebutton 21, the elastic force of thespring 15 causes the rearward extendingportion 42 and the elongatemetal locking bar 2 to move forward together. The grooverear wall 81 of thetransverse groove 8 urges the turntable 3 to reset by pushing the secondcircular projection 7. - As shown in
Figures 14 to 16 , when the turntable 3 is manually rotated via thebutton 21, the secondcircular projection 7 on the turntable 3 is always moved in thetransverse groove 8, and the secondcircular projection 7 applies a force acting on the grooverear wall 81 of thetransverse groove 8 in a direction perpendicular to the grooverear wall 81, that is, the direction of the force is the same as the movement direction of the rearward extendingportion 42, which ensures that the force is not decomposed and sufficiently acts on the rearward extendingportion 42. - As a result, the
button 21 may be manually rotated more easily and smoothly. In this regard, the second embodiment has some advantages relative to the first embodiment. In the first embodiment, theelongate slot 5 on the turntable 3 and the first circular projection 6 on the rearward extendingportion 42 are in a working relationship, and the direction of the force acting on the first circular projection 6 by an inner wall of theelongate slot 5 and the movement direction of the rearward extendingportion 42 are not necessarily coincident with each other at all times. Therefore, the locking apparatus of the second embodiment may be easily operated with less effort. - In this embodiment, the forwardly extending
portion 41 of connectingmember 4 comprises afirst channel 12 for receiving the elongatemetal lock bar 2 where the first channel is located on a lower side of the forwardly extendingportion 41. Thefirst channel 12 compriseslimit ribs 13 for limiting the up-and-down movement of the elongatemetal lock bar 2 and which are located on two sidewalls of thefirst channel 12.Forwardly extending portion 41 further includes a throughhole 14 located on an inner end. - The retained end of the elongate
metal lock bar 2 is bent at 90 degrees to form aforce receiving end 211 which may be inserted in throughhole 14. The shape of thefirst channel 12 and throughhole 14 matches with that of the elongatemetal lock bar 2 after being bent at 90 degrees. When theforce receiving end 211 is contained in thefirst channel 12, it is also fixed by thelimit rib 13. On assembly, when the connectingmember 4 linearly reciprocates on operation ofbutton 21, the elongatemetal lock bar 2 which is confined within thefirst groove 12 is similarly caused to linearly reciprocate. - As shown in
Figures 14 to 16 , when the locking apparatus is used, the turntable 3 is rotated around its axis of rotation by rotating thebutton 21, the secondcircular projection 7 on the turntable 3 is constrained to move in thetransverse groove 8, and the direction of the force applied by the secondcircular projection 7 on the grooverear wall 81 of thetransverse groove 8 is perpendicular to the grooverear wall 81, resulting in the rearward extendingportion 42 and thespring 15 contained in theU-shaped groove 17 moving backwards together. Thespring 15 is gradually compressed due to being compressed by the secondend abutment portion 112 until the secondend abutment portion 112 stops at the distal end of theU-shaped groove 17. - At this time, the elongate
metal lock bar 2 is completely moved out of the lock hole of the cage body and small animals may be taken out or put in by opening the door body. When thebutton 21 is released, the elastic force of thespring 15 causes the rearward extendingportion 42 and the elongatemetal locking bar 2 to move forward together. As a result, the grooverear wall 81 of thetransverse groove 8 urges the turntable 3 to reset by pushing the secondcircular projection 7. - When it is necessary to close the door body, the turntable 3 is first rotated so that the
spring 15 is in a compressed state. Thereafter, when the outer end of the elongatemetal lock bar 2 is aligned with the lock hole of the cage body, the turntable 3 is released. As a result, the restoring force of thespring 15 will cause the elongatemetal lock bar 2 to be inserted into the lock hole of the cage body and the door body is locked by the locking apparatus. - As would be appreciated by those of skill in the art, a locking apparatus in accordance with the present invention includes as an advantage that rotating the turntable around its centre point results in the simultaneous linear movement of the one or more elongate metal bars to cause the locking or opening of the door body. This arrangement is very convenient and ergonomic to operate and effectively locks the door body to the cage body as has been described above.
- In addition, the configuration of the connecting member provides an arrangement where a pair of elongate metal lock bars can extend in opposed directions from the centre of the locking apparatus with respect to the turntable and this configuration provides improved stability of the locking apparatus as the forces are balanced. Another advantage is that connecting the elongate metal lock bar to the connecting member does not require multiple bends in the elongate metal lock bar.
